Original mama filed'June 27, 1910, Serial No. 569,058. Divided and 1912. Serial No. 693,607.

To all whom itmag concern Be it known that we, WILLIAM L. WARD, HERBERT D. RnMsnN, and EMILE C. Bonn- NER, citizens of the United States, residing at Port Chester, in the county of Westchester and State of New York, havev invented certain new and useful Improvements in N ut-Making Machines, of whichthe'followering means such as a transfer mechanism,

will thereupon accurately bring such an article into successive positions 1n each of which it may be acted upon by a die or the like provided in a machine such, for exam- I ple, as that set forth in a copending application filed June 27, 1910, Serial No. 569,053, patented February 24, 1914, No. 1,088,192,

I of which this application is a division.

One object of the'invention is to provide a mechanism whereby a blank, and especially a nut-blank, may be seized initially and thereupon passed successively into the action of each of a plurality of implements while always held in the original grip; thus avoiding inaccuracies arising from slight changes in position of the blank in its, holder.

Another object is to adppt for a conveyer delivering a train of blanks a mechanism for successively removing blanks from the delivery end thereof and to subject such blanks to a series of forming operations, without having the precision and regularity of the operation impaired by the ordinary variations in the travel of the train of blanks.

Other objects and advantages Will be in part pointedout hereinafter and in part rendered apparent by means of the accompanying illustrations. M r i 5 The invention accordinglyconsists in the features of construction,combinations of Q18? ments and arrangement of parts which will .ee mp fi nth co t u on herei after set forth, and the scope ofthe application of which will be indicated in the following claims.

The c0nveyer.-Turnin to Fig. 1, there will be seen a track-like slide 238 which will normally be loaded with blanks which will be successively introduced into one end, and pushed along toward the discharge end from which they are successively removed by the apparatus 'now to be described.

The mechanism for transferring the nutblanks from the conveyer to the roulette. It may be perceived at this point that, owing to the somewhat rough and irregular contour of the nut-blanks which are pushed along the conveyer in vthevform of a long train of blanks, the foremost nut-blank may be more or less displaced in its position. That is' to say, at one time the foremost unit of the train of nut-blanks may be Well advanced with respect to the extremity of the conveyer, and at another time it may be positioned more to the rear of such extremity. On the other hand, in an automatic machine of this character one highly important attribute to smoothness and positiveness of action will reside in an accurate and unfailing placing of the nut-blanks. In order, therefore, to. provide a mechanism having the capacity of compensating for the variable positions of the nut-blanks at the delivery end of the conveyer, this invention proposes to intervene what may be termed a picker mechanism between the conveyer and the roulette which carries the nuts through the var ous finlshing operations, such as crown ing, repunching, retrimming and the like.

According to this invention a device such as that shown by Fig. 3 and comprising a pair of tong-like spring arms is mounted adjacent the extremity of the conveyer and adapted to horizontally reciprocate so as to advance into engagement with the nut-blank carried at the end of said conveyer and withdraw the same therefrom, and thus positively position the same in a predetermined vertical plane. This mechanism is shown more plainly by Figs. 2 to 6 inclusive.

Turning first to Figs. 3 and 4, a pair of spring fingers or tongs 240 and 241 are secured, by means of screws such as 242 to a block 243 so as to lie parallel with one another, but spaced apart approximately somewhat less than the maximum diagonal ofa nut-blank. This block 243 is mounted to slide in a horizontal direction in a suitable stationary part of the frame of the machine, as shown by the drawings, and is actuated through in the slotted end 245. An actuating lever 246 is pivoted at its one end to the pivot pin 247 and at its other end carries the pin 248, which moves in the slot in the end 245. This lever is actuated by means of the roller 249 which rides in contact with the peripheryof the cam 250 which is fixed to shaft 251 mounted in journal boxes 252 arranged at one'side of the machine. held in contact with cam 250 by any suitable' means, such as the usual spring. This shaft is in turn driven by the beveled gear 253 in mesh with the gear 72 which is secured to the shaft 72, which at one end ca-rries the gear 254 in mesh with the gear 255 mounted on the main shaft 6. As a result of this mechanism, the spring fingers or tongs 240 and 241 are caused to advance toward the end of the nut-blank conveyer 238 and, by reason of the slot 239 they are able to pass over and frictionally grip the nut-blank at the head of the train of blanks. Consequently, during the withdrawal of the spring fingers or tongs 240 and 241, this nut-blank will be removed and carried to a position such that it may be engaged by a second pair of tongs which are arranged to slide vertically and transversely to the movement of said first-mentioned tongs. The'second tongs are shown more clearly by Figs. 5 and 2 and indicated by reference numerals 256 and 257. These second tongs are secured to a block 258 fixed to a member 259, Whichis in turn adj ustably fixed in position on a vertically reciprocating block 260 by means of the screws 261. This block slides vertically in the ways 262, and has a pivot pin an extension 244, which terminates.

Roller 249 may be 263 projecting rearwardly through slot 264 in the vertical ways 262 (see Fig. 7 This pivot pin 263 carries a conventional form of sliding block which slidably connects with the end 265 of the vertically oscillating lever 266. This lever is pivoted at its distant end to the pivot 267 and is actuated by means of an intermediately located roller 268 in engagement with the cam 269 (see Figs. 2 and 6), also fast to the shaft 251.

It will, from the foregoing, be understood that when the first tong mechanism withdraws the nut-blank from the end of the conveyer, such blank is to be transferred to the vertically moving pair of tongs. This is accomplished by means of an upper plunger 270, which reciprocates between the tongs 240 and 241, and which is normally held in a retracted position by means of the spring 271 (see Fig. 2). At the proper instant, this plunger is advanced and pushes the nut-blank from between the tongs 240 tion through the operation of the lever 266.

Themeans for operating the plunger 270 consists in a lever 272 (shown more-clearly lever 272 is actuated. by means of a rol1er 275 which contacts with the cam 276 fixed 'to.the shaft 251. A spring 277 (shown in Fig. 2) operates to keep the roller 275 properly pressed against the cam surface 276. Tzhe spring 277 is stronger than the spring 2 1;

In order to transfer the blanks from the vertically moving tongs, this invention proposes a lower plunger 278. This is shown more clearly by Figs. 5, 6 and 7. This plunger 278 reciproc'ates horizontally and is pivotally connected with an uprising bent lever 279, which is pivoted at 280, and at its upper end carries the roller 281 which rides around the cam 282 and is intermittently actuated thereby.' Roller 281 may be held in contact with the cam 282 by any suitable means, such as-the usual spring. Consequently, each time the plunger'278 operates, a nut-blank will be forcedfrom the vertically movingtongs and will be received by the adjacent spoke of the roulette or spokelike structure, as will be presently described. Through this mechanism the blanks are very certainly and accurately positioned and transported through the several finishing operations.

The roulette for carrying the nut blanks through the successive fimhz'ng 0peratz'0ns. The detailed construction of the preferred form of roulette is shown more particularly by Figs. 8 and 9. A shaft 283 passes from the rear or discharge end of the machine through the main frame, and terminates adjacent the end of the double-headed reciprocating punch-carrying frame. At its forward end, this shaft tapers and carries the hub 28& of the roulette. This hub is securely retained in position by means of a pressure plate 285, which is positioned by the nut 286 on the end of the shaft 283. The hub of this roulette provides a series of equispaced radiating spoke-like members 287, 287, 287 and, inasmuch as these are similar in character, but one need be described. This radiating portion extends to the rear, 2'. c., in an axial direction, a little less than one-half the total length of the hub 284 and provides -a grooved channel or trackway in which an intervening block 288 may slide in a radial direction, but is restrained against any other movement relative to the part 284 A tong-block 289 has a transverse movement which is pivoted at an on the intervening block 288, as shown more clearly by Fig. 9, so as to permit of slight lateral adjustment of such block if desired. The block extends forwardly in the form of a shaft 290 which carries the nut 291 at its foremost extremity. This nut enables the parts to be secured rigidly in place by clampwith su cient firmness by reason of the spring tension of the arms or fingers 294 and 295. These fingers are in turn secured to the tong-blocks 289 by means of appropriate nuts and bolts, indicated by 297. This roulette is arranged and disposed as shown more clearly by Fig. 1, so that as the shaft 283 is intermittently rotated through an angle of degrees, the blank supporting devices, or spring fingers, of the roulette will successively pass by a position directly opposite the plunger 27 8 which forces the blank from the abovedescribed vertically moving carrier to the finger of the roulette Forthe purpose of se-- any which is at the instant in registry therewith. v

In this Way every-time the plunger 278 operates, a nut-blank will be positioned in the roulette. The blank-is first carried through a sixth of a revolution of the roulette, as indicated by the arrow on Fig. 8, so as to bring it into position opposite the flattening punch 298 which ismounted on one end of the double-ender reciprocating punching head. The nut-blank is side by the anvil 299 which is adjustably mounted in the stationary part of the main supported from the other frame as by means of the adjusting screw 300. This is shown best by Fig. 9. After this operation, the roulette is again turned through 60 degrees, bringing the blank opposite the crowning-die 301, shown in front end elevation by Fig. 8 and in rear elevation by Fig. 10. This crowning-die has the form of an elongated cylinder which is se cured to the main frame by means of the engaging screw threads 302, and is adjusted therein by turning the nut forming its rear, exposed end. The working end of this die is countersunk, as indicated by 303, so that, during-the advance of the plunger 304: carried by the reciprocating head, the nut-blank will be forced into this recess 303 and thus be given a crown. It may be stated in this connection that since the forces em ployed during this operation are considerable, there is a tendency for the nut-blank to more or less firmly adhere to the die 301, and to that end means are provided for forcing the same out of such die to enable the crowned blank to'be carried along by the spring arms of the roulette and positioned opposite the repunching' die. This ejector consists of a plunger 305 which reciprocates in the central bore of the crown-die 301 and which may assist in partially forming the crown. This plunger 305 preferably has enlarged bearing portions 306 and 307, and protrudes from the rear of the frame in the form of a screw-threaded shank 308 which relative thereto. by means istapped to the gudgeon bolt 309 and locked thereon by means of the nut 310. This gud- 'geon bolt provides usually right and left bearing pins or dgeonsi311. These pins are seated in the bifurcated ends 312 of the safety lever 313. This lever is of compound character, and comprises an upper member 314 which is pivoted to the lower member 313 by means of the pivot pin 315, but is normally prevented from angular movement of the safety shear pin 316. This shear pin 316- is constructed of steel sufliciently soft to give Way under r at its upper extremity excessive strains so as to prevent fracture of other parts of the mechanism. This lever is in turn secured to the end of the shaft 317, which is mounted in bearings 318--secured to the rear end of the stationary frame,

and at its-other end this'shaft carries the roulette to the retrimming-die 327, shown on Figs. 8 and 9. This retrimming-die has a hexagonal aperture of appropriate size, and

, when the plunger 328 carried by the main forced through inturn ultimately are discharged through reciprocating head advances, it will force the nut-blank through this hexagonal aperture in the retrimming-die 327', thus shaving off any excess metal on the edges of the blank. Through the successive movements; of the plunger 328,

the die 327, and these blanks the aperture 329, shown by Fig. 10.

The automatic rotator for the roulette- In the foregoing it has been stated thatthe roulette turns intermittently through angles of degrees for the purpose of successively presenting the nut-blanks carried by the fingers thereof through the several finishing operations. disclose the means instrumental in automati- Muv nvnriunino' this motion of the roulette.

the train of blanks is then It now becomes necessary to Preliminary to adescription of this, .it may be pointed out'that it is essential that the I travel of the roulette shall be very accurately determined so that the blanks may be brought to the. exact positions, and inlike manner it is equally essentialfthat' when these successive positions have been attained, the roulette shall be looked a gainst any slight displacement due. to backlash or other causes. This mechanism contains provision for accomplishing these objects-and the same may be best understood by referring to Figs. 10, 11 and 12.

The shaft 283 to which the roulette is s'ecured, projects rearwardly. from the main frame ofthe machine and carries three notched wheels, the one .beingin the nature of a ratchet wheel adapted to co-act with a ratchet mechanism in turning the roulette, the second in the nature of a stopv wheel adapted to co-act with a removable stop in limiting the movement in one direction, and the third being in the nature of'a stop wheel adapted to co-act with another stop (which is also a safety device) in limiting ,the movement in the opposite direction, and-thus 'coact with the second wheel in bringing the roulette to a fixed stationary and accurately determined position.

The ratchet wheel 342 is keyed fast to the shaft 283 a slight distance fromthe end of the same, and this cupied by the hub 343 of the oscillating ratchet carrier 344. This hub is retained in place by means of an end-plate 346- which is held on the shaft by. means of the nut 347. The upper extremity'of the ratchet carrier remaining distance is 00- 344 is provided with the ratchet 345 which I extends downwardly into' engagement with the ratchet wheel 342. This ratchet carrier is oscillated through-the instrumentality ofthe reciprocating lower end, is pivotally connected between the two arms 349 of the ratchet carrier.

This arm 348 derives its movement from a roller 350 which rides in contact with the earn 351. Its other extremity352 may be prevented from side play in any suitable manner, as by connecting the, same by sliding block with the shaft 251, as will be readily understood. In consequence with this arrangement a rotation of the shaft arm 348, which, at its of the wheel 354,

through the link 355 moved by the actuating lever 356. This lever is pivoted at an intermediate point 357 to the main frame of the machine and its upper end carries the roller 358 which rides in contact with the periphery of the cam 359, so that during each revolution of the shaft 251 the stop lever 353 will be withdrawn to enable the roulette to be turned and will then be thrown back in place to cause an arrest of its forward rotation at the precisely determined point. Roller 366 may be held in contact with the cam 367 by any suitable means, such as the usual spring.

In order to prevent any reflex action of the roulette, this invention also proposes the third notched wheel 360 which is adapted to be engaged by the suitably pointed end of the plunger 361 which is suitably supported in the bearing 362 adjustably mounted on the main frame of the machine. The rear end of the stop plunger 361 provides the two gudgeons 363 which are engaged by bifurcated end 36L of the actuating lever 365. This lever is pivoted at an intermediate point and atits upper end carries a roller 366 which is actuated by the cam 367. Accordingly, as this cam rotates, the lever 365 will be intermittently operated thus producing a reciprocating action in the stop plunger 361 and thereby releasing or locking the roulette wheel in position as ma 354 and'36'0 move with the shaft 283.

By the above described construction is efficiently and accurately accomplished,

among others, the objects hereinbefore men- I tioned. The roulette which supports the nut blanks, and the implements, such as the punches and dies which operateupon the nut blanks and reshape, or refinish, the nut blanks as explained, are associated in a compact structure which yet permits the parts to be made of suflicient size to possem the requisite strength to stand up under the relatively heavy pressures engendered. The gripper fingers 294 and 295, are disposed to support the nutblanks on opposite sides by engagement with peripheral portions of the blanks, so that the faces of the blanks are clear and may be readily operated upon by the punches and dies; The nicks 296 in a measure positively prevent radlal movement of the blanks relative to the fingers, so that though the roulette is disposed to rotate in a vertical plane, there is practically no danger of'the blank being radially displaced. Thus the nicks assist the grip of the fingers in retaining the blanks from radial displacement. The punches and dies coiiperate in a line which intersects the rotary path of the gripper fingers, being relatively movable in such line, the dies being preferably fixed in order that the prime reshaping elements shall remain in the desired radial and circumferential relative positions oppositebe appropriate at the instant.
